In this week's Lost & Found Sound feature, "Quest for Sound" curator Jay Allison guides us through a collection of voices of American servicemen. They come from the 1,500 callers who contacted us all this year to tell us about tapes and discs they have at home. Many were made at Christmas or during wartime. We hear from a father in Vietnam corresponding by cassette with his family. We also hear a rare recording of the five Sullivan brothers of Waterloo, Iowa, who lost their lives on the USS Juneau — along with 700 other men — in November 1942. And, we hear the testimony by a former Korean War prisoner about the worms in the rice he was fed; a Gulf War conversation between brothers abroad and at home — cut short by a Scud attack; and a veteran of the trenches of World War I telling about surviving five days in No Man's Land with two legs and an arm shot up.
